Sparrow is truly one of the best email clients for the Mac. It has a very simple inbox with excellent support for GMail labels, as well as dropbox support for attachments. The interface is top notch, even rivaling Apple's own Mail app. Unfortunately, Sparrow is no longer developed except for minor bug updates. Despite that, it's still a great choice.
